+##### http://autoconf-archive.cryp.to/acx_blas.html
+#
+# SYNOPSIS
+#
+#   ACX_BLAS([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro looks for a library that implements the BLAS
+#   linear-algebra interface (see http://www.netlib.org/blas/). On
+#   success, it sets the BLAS_LIBS output variable to hold the
+#   requisite library linkages.
+#
+#   To link with BLAS, you should link with:
+#
+#   	$BLAS_LIBS $LIBS $FLIBS
+#
+#   in that order. FLIBS is the output variable of the
+#   AC_F77_LIBRARY_LDFLAGS macro (called if necessary by ACX_BLAS), and
+#   is sometimes necessary in order to link with F77 libraries. Users
+#   will also need to use AC_F77_DUMMY_MAIN (see the autoconf manual),
+#   for the same reason.
+#
+#   Many libraries are searched for, from ATLAS to CXML to ESSL. The
+#   user may also use --with-blas=<lib> in order to use some specific
+#   BLAS library <lib>. In order to link successfully, however, be
+#   aware that you will probably need to use the same Fortran compiler
+#   (which can be set via the F77 env. var.) as was used to compile the
+#   BLAS library.
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a BLAS
+#   library is found, and ACTION-IF-NOT-FOUND is a list of commands to
+#   run it if it is not found. If ACTION-IF-FOUND is not specified, the
+#   default action will define HAVE_BLAS.
+#
+#   This macro requires autoconf 2.50 or later.
